Abbreviates labels to a maximum length, adding ellipsis if truncated.
Usage
abbrev_label(label, abbrev = NULL, n_labels = NULL)
label_abbrev(label, abbrev = NULL, n_labels = NULL)Arguments
- label
Character vector of labels to abbreviate.
- abbrev
Abbreviation control:
NULL: No abbreviation (return labels unchanged)
Integer: Maximum character length (truncate + ellipsis)
"auto": Adaptive abbreviation based on label count
- n_labels
Number of labels (used for "auto" mode). If NULL, uses length(label).
Examples
labels <- c("VeryLongStateName", "Short", "AnotherLongName")
# No abbreviation
abbrev_label(labels, NULL)
#> [1] "VeryLongStateName" "Short" "AnotherLongName"
# Fixed max length
abbrev_label(labels, 5) # "Very...", "Short", "Anot..."
#> [1] "Very…" "Short" "Anot…"
# Auto-adaptive
abbrev_label(labels, "auto")
#> [1] "VeryLongStateName" "Short" "AnotherLongName"
